Our Products
The Gang operated load break switches are meant for outdoor application and are suitable for horizontal or vertical mounting. They are designed for satisfactory performance in harsh atmospheric conditions of high/low temperatures & humidity. Their primary function is to isolate a 33kV, 3 Phase network.
FEATURES
* Single break type with 2/3 post insulators per pole. Quick make & break manual operation.
* Suitable for operation upto a altitude of 3000 m.
* Suitable for mounting at the top of a single or double steel pole.
* Used for single / three phase applications and suitable for operation on structures 6 meters or more above ground level with a pad lock facility.
* Robust sturdy design with bottom MS channel of adequate dimensions which imparts requisite strength.
* Copper contacts are made of ETP grade high conductivity copper and are spring loaded for adequate contact pressure. The contacts are duly plated to improve resistance to corrosion and offers a low resistance current path.
* All MS parts and Hardware are duly hot dip galvanized as per standard specifications which imparts long life to the switch.
* The Isolator is capable of withstanding the electrical & mechanical stresses induced during unlikely event of a short circuit.
* Sturdy operating mechanism is provided allowing easy operation 6 meters or above ground level with simultaneous operation of all the three poles making perfect electrical contact. Mechanical locking facility is provided for closed & open positions as required.
* The Post insulators are with min. creepage distance of 1150 mm suitable for heavily polluted atmosphere and meets the stringent requirements of IEC.
* The operating GI pipe provided along with the switch conforms to Medium Class as per IS 1239-1/ Eqvl and is 6000 mm in length.
* A choice of terminations can be provided to suit individual customer requirements.
It consists of manual/motor operated spring charged mechanism of stored energy type.
In the closed state of breaker, the closing spring can perform the duty operation. Facility is also available for hand charging the springs in the event of control supply failure. The closing spring is charged in less than 15 sec. Electrical Anti-pumping feature is also provided.
The mechanism is trip free and suitable for rapid Re-closing. The vacuum interrupters are capable of switching capacitive currents and small Magnetizing current.

The fabricated enclosures/housings undergo a process of chemical pretreatment as per laid down procedures before being powder coated.
Our standard range of fuse carriers are made from DMC which has high impact & di-electric strength and are suitable for BS-88 HRC fuse links. The FuseCarriers are available in 82.5 & 92 mm fixing centers in Finger grip, and Through grip options. The fuse carriers are also available in porcelain with 82.5mm fixing centers.
The Surge Arrestors are an indispensable protection devise which needs to protect a transformer against natural lightning & switching surges in a high voltage system. They are designed for satisfactory performance in critical atmospheric conditions of high/low temperatures & humidity. Asiatic offers the latest Gap less Metal oxide technology which is far superior than conventional systems being used previously in terms of vast improvement in VA curves & increased through current capability at over voltages. Features
he Gang operated Air break switches are meant for outdoor application and are suitable for horizontal or vertical mounting. They are designed for satisfactory performance in harsh atmospheric conditions of high/low temperatures & humidity. Their primary function is to isolate a 11 kV, 3 Phase network. Asiatic manufactures the Air break switches in both Porcelain & Silicone rubber versions.
Features
* Single break type with 2 or 3 post insulators per pole depending on requirements of the customers.
* Can be used for single or three phase applications.
* Robust sturdy design with bottom MS channel of adequate dimensions which imparts requisite
strength.
* Self lubricating central bush bearing in 2 or 3 insulator design of air break switches allows easy
operation.
* Copper contacts are made of ETP grade high conductivity copper and are spring loaded for adequate contact pressure. The contacts are duly
plated to improve resistance to corrosion and offers a low resistance current path.* The Post insulators are available in Porcelain and Silicone Rubber with large creep age distance suitable for heavily polluted atmosphere and meets the stringent requirements of IS/IEC standards.
* All MS parts and Hardware are duly hot dip galvanized as per standard specifications which imparts long life to the switch.
* In 3 insulator design, tin plated braided Copper wire of adequate cross section is provided as per rating of the GOAB switch and depending upon customer requirements.
